Pulsing

Hay team so out of nowhere my l701 started pulsing when idle starts and drives all good but after its warmed up thats when it starts, if i remove the map it runs find no pulsing (only on the drive way)

Was told map sensor have replaced also got told hoses (vacuum) may be blocked so replaced all them also,

Anyone had this problem

Idle adjustment?

Cheers team

yes mine was the cold start solenoid. I removed and plated mine off the throttle body. Harder to cold start but not an issue again.
